APPARATUS FOR GRlNDlNG FLATS OF CARDlNG-ENGlNE-IS.

SPEOIFIGATION forming part of Letters Patent No. 491,356, dated February'7, 1893. Application filed June 2, 1892. Serial No. 35,296. (No model.)Patented in England April 18, 1889, No. 6,621

To ttZZ whom it may concern:

Be it known that I, JOSEPH JONES, a subject of the Queen of England,residing at Dukinfield, in the county of Chester, England, have inventedcertain new and useful Improvements in Apparatus for Grinding the Flat-sof (Jarding-Engines, (for which I have obtained Letters Patent in GreatBritain, No. 6,621, hearing date the 18th day of April, 1889,) of whichthe following is a specification.

This invention relates to that class of apparatus in which the revolvingflats of carding engines are ground from their working surfaces toobtain a uniform grinding of the wire; or in which the weight of thejournal of the grinding roller is sustained by the working end of theflat while the wires are being ground.

The invention will be fully described with reference to the accompanyingdrawings.

Figure 1. is a front elevation of apparatus. Fig. 2. a back elevation.Fig. 8. a side elevaticn. Fig. i. a back elevation partly insection withthe horn bracket removed.

The horn bracket A is of the usual construction with a horn orprojecting piece a which raises and supports the several flats B as theyare carried forward to the ground. It will be understood that there aretwo of these brackets one attached to each side .of the card and thatthe other parts mentioned are also in duplicate one at each side of thecard the grinding roller and flats passing across the top of the cardthe supports at both sides being alike. Hence for convenience ofdescription I have only shown and described one invention.

The horn bracket Ais bolted to the side of the card and remains firm andstationary. It is provided with a fixed bracket or slide 0 to which isfitted a sliding bracket D. The sliding bracket D is free to move to andfro in a vertical direction and at its upper end it carries the journalE for the grinding roller. I attach to this sliding bracket D by meansof a screw it or other adjustable device a guide plate or bracket Fagainst the under surface of which the flats B successively bear as theypass forward over the horn a of the horn bracket A. The under surface ofthe guide plate F is formed as shown with two surfaces f f inclined toeach other, the surface f being at right angles to the longitudinal axisor direction of movement of the sliding bracket D and the surface fbeing inclined thereto a small step f" separating the junction of thetwo surfaces. The guide plate F is carried by the adjusting screw (1which passes through a lug at the back and is secured in position by thebolt d passing through it and the sliding bracket D. The flats areraised by and slide over the horn a of the horn bracket A in the usualway resting on a flat planed surface on the under side of each flat andwhen not desired to be ground pass beneath the grinding roller at alittle distance from it. lVhen it is desired to grind the flats a smallremovable lifting plate G is placed on the horn bracket A inside thehorn a over which the curved under surface I) of the flats slide and bywhich they are raised up into contact with the inclined guide plate F.The guide plate is adjusted and lined relatively to the journal E of thegrinding roller to give the amount of grinding required; the flats arelifted into position by the lifting plate G with their working surfacesagainst the guide plate F; and the inclined under surface of the guideplate F tilts or heels the flat to give the required inclination of thewires being ground, the fiat being free to heel by reason of a curvedsurface bearing upon the lifting plate G.

"What I claim and desire to secure by Letters Patent is:-'

1. In apparatus for grinding the flats of carding engines thecombination with the fixed horn bracket A provided with a slide 0 of theupright sliding bracket D carrying the journal E, the guide plate Faffixed to the sliding bracket D and moving up and down with it and theadjusting screw d substantially as described.

2. In apparatus for grinding the flats of carding engines thecombination with the fixed horn bracket A slide 0 and sliding bracket Dwhich carries the journal E of the guide plate F the under side of whichis provided with two surfaces one at right angles In testiinonywhereofIhave signed myname to and the other at an inclination to the axis tothis specification in the presence of two subof the sliding bracket 1)to heel or tilt the scribing witnesses.
